Electrophysiological studies of photoreceptors from the horseshoe crab Limulus polyphemus continue to provide fundamental new knowledge of the photoresponse in invertebrates. Therefore, it is of particular interest to characterize the molecular compo

Fundulus heteroclitus naturally spawns with a semilunar periodicity throughout most of the year in its southernmost habitat, an activity that can be maintained in the laboratory. The alpha and two beta subunits comprising F. heteroclitus gonadotropic

The data reviewed here show that histamine, octopamine, and serotonin are abundant in the visual system of the horseshoe crab Limulus polyphemus. Anatomical and biochemical evidence, including new biochemical data presented here, indicates that hista

The biweekly spawning teleost, Fundulus heteroclitus , is an interesting biological model that has its spawning cycle synchronized with the tides coincident with the new and full moon. Changes in the dopamine (DA) and serotonin (5-HT) contents in the

In rhabdomeral photoreceptors, light stimulates the phosphorylation of arrestin, a protein critical for quenching the photoresponse, by activating a calcium/calmodulin-dependent protein kinase (CaM PK). Here we present biochemical evidence that a CaM

The patterns of vitellogenesis and follicle maturational competence were examined across the semilunar spawning cycle of Fundulus heteroclitus. Daily egg collection showed spawning cyclicity in six experimental groups, with a mean period between spaw

The ommatidia of the lateral eye of the horseshoe crab, Limulus polyphemus, undergo rhythmic changes in structure that are driven by diurnal lighting and efferent neural activity from a circadian clock in the brain. This study uses cytochemical probe

Studies of lateral, median, and ventral eyes of the chelicerate arthropod Limulus polyphemus (the common American horseshoe crab) are providing important basic information about mechanisms for information processing in the peripheral visual system an

Histamine has been proposed as a photoreceptor neurotransmitter in two major groups of arthropods, the insects and the crustacea. In this study biochemical and immunocytochemical approaches were used to examine the synthesis, endogenous content, and

The photoreceptors of the horseshoe crab Limuluspolyphemus are classical preparations for studies of the photoresponse and its modulation by circadian clocks. An extensive literature details their physiology and ultrastructure, but relatively little
